amandahostsauth failed
Hi all, I'm trying to configure a backup server, but it isn't working... My client is 192.168.20.81 and my server is 192.168.20.156 I want to make the back of /tmp and /etc My client's port: 10080/tcp closed unknown 10081/tcp closed unknown 10082/tcp closed amandaidx 10083/tcp closed amidxtape My server's port: 111/tcp open rpcbind 113/tcp open auth 916/tcp open unknown 10080/tcp closed unknown 10081/tcp closed unknown 10082/tcp open amandaidx 10083/tcp open amidxtape My log file is (I change my domain): START driver date 20050402 DISK planner 192.168.20.81 /etc DISK planner 192.168.20.81 /tmp START planner date 20050402 INFO planner Adding new disk 192.168.20.81:/etc. INFO planner Adding new disk 192.168.20.81:/tmp.

You need an .amandahosts file on the client (in your backup user's home directory, and not world readable) containing: foghorn.MYDOMAINbackup and remember to replace MYDOMAIN with whatever was in the 'ERROR' message you quoted above.

Re: amandahostsauth failed
Thank You. The backup is working... but when I try to restore it, it isn't working... foghorn:~#amrecover AMRECOVER Version 2.4.4p3. Contacting server on localhost ... 220 foghorn AMANDA index server (2.4.4p3) ready. 500 Access not allowed: [access as backup not allowed from [EMAIL PROTECTED] amandahostsauth failed Do someone have some hint ? Thanks for the help - Vinicius

First, don't use 'localhost' in your disklist or anywhere else, it will cause problems later (see the list archives for full discussions of why). Second, on the Amanda server (which could also be a client) you need to add a line to your .amandahosts file for each client to allow root to restore from that client: client.domain root If you really need to restore the backup you just made, using locahost would work if the client is also the server, but is NOT recommended. localhost won't work if the client is on a different machine, or if someday you change servers.

I would like to challenge this statement. I don't normally bite on challenges, but I'll take up this one. I hope you read into my statement that I meant amanda vs human, both using the amanda 'manager and scheduler' software. I say it that way as amanda is not a backup "program". > It may be true if you have a large network of systems to back > up but if you only have one system I doubt if it's true. Did you miss that amanda is an acronym for: Advanced Maryland Automatic NETWORK Disk Archiver The needs of a site with one system are very different than those of a site with a network of systems for which amanda was intended. The fact that it can be used very effectively on a single system is a testament to its flexible design. > Before my switch to Linux I backed up my system > (OS/2) on a weekly schedule with one full back-up and four incremental > back-ups to one tape only.

I could probably do with less tapes > but I feel more confident with a large tape pool. On my home site I do have amanda backup more than one system. But I only care about one. The others are "test" systems. I will often reinstall the OS from scratch on them. For example, I have HP-UX and Tru64 unix systems just because I have clients who use those OS and I like having one available to practice with. The one host I do care about has about 150GB of disk with about 40GB filled. One thing that may be different from your environment is that I've broken it down into about 15 DLE's. By keeping the DLE's small individually, amanda's scheduler can balance when to do level 0's of each DLE throughout the dumpcycle and lets me do daily backups to a single DDS3 tape. Even when I've downloaded a couple of new CD's, amanda adjusts and rebalances its schedule seldom requiring two tapes in a day. I have not worked with OS/2 for over a decade. From that experience I recall a backup "program", analogous to dump or tar. I don't recall a backup "system" one that for example tracked the tapes used and reused them in the correct order, maintained indexes of files on which tapes, had interactive or batch recovery, dynamically and automatically adjusted for missed backups or tape errors, allowed for flexibility in time between level 0's on a file system by file system basis, adjusted the incremental level based on the amount of change in the file system, ... The OS/2 backup program I remember did nothing more than I can do with dump and a little shell scripting. Was there a backup "system" added to OS/2 of which I'm unaware? What features of that system did you find useful? > > I would add that I haven't yet found out how to keep a repository of > back-ups of the previous weeks like I was used to with OS/2.

I too am more confident with a large tape pool, but I have 24 in rotation, rather than 9. With that collection I find it simple to recover files as of a specific date anytime within the last 3-plus weeks. I'm a keyboard user from wayback. Literally mice did not exist when I started with unix. There are times when I must deal with email using a GUI program like ThunderBird or (horrors) LookOUT. They make me use the mouse and I hate it. I go back to my prefered, mouse-less program, mutt as soon as possible. I have always felt that one should use what meets their needs and with which they are comfortable. Amanda is certainly not the answer for every backup requirement. For one current client I'm using rsync to meet their needs and comfort level. Based on your described use of your backups and your lack of comfort with amanda's scheduler, might not a set of shell scripts and dump or tar be a suitable, perhaps superior solution for your needs than amanda? -- Jon H.

Next, how often do you expect to run amanda between level 0 (full dumps). This is amanda's "runspercycle" parameter. Say you are running amanda daily and you want a level 0 each week, there would be 7 runs/cycle. Remembering that amanda spreads its level 0's over all the runs gives us 280GB / 7 runs or an average of 40Gb of level 0 dumps per day. Adding in a bit for daily incrementals and some for daily variability, maybe 60GB per tape would be needed. That would seem to be 8 tapes of 60Gb == 480GB. If the 480GB were all from on pool/file system, I'd be tempted to suggest you allocate tapes beyond the apparent capacity of the file system. If you create an 80GB vtape, it does not take 80GB of the 480. It takes whatever is written to that tape during an amanda run. So if you create 8x80GB, or 10x70, as most tapes will only have 45-60GB of data written to them, it may never exceed the 480GB. If it does, amanda will react like it would to a broken physical tape. -- Jon H.
